如何在delve中打印字符串变量的完整值？

I'm using the delve go debugger to debug some code. When I try to print a string variable, it gives me an abbreviated version.

(dlv) print myString
"my string...+539 more"

How do I get it to print the full string?

The ability to configure the length of printed strings was recently added to delve. To see the full list of configuration options, run config -list;

(dlv) config -list
aliases            map[]
substitute-path    []
max-string-len     <not defined>
max-array-values   <not defined>
show-location-expr false

The one we're interested in here is called max-string-len, which you can see is currently <not defined>. To increase the length to e.g. 1000, run

(dlv) config max-string-len 1000

Now running print myString should print the whole string.

Just to add to your answer, if you're using VS Code debugging feature, add the following config to your settings.json:

    "go.delveConfig": {
        "dlvLoadConfig": {
            "maxStringLen": 1024,
        },
        "apiVersion": 2,
    },
